Specific embodiments
[0020] The following is a description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.
[0021] Referring to the attached Figures 1-4 , a marking and dotting device for pressure welding provided by the present invention includes a base 100. At the top end of the outer wall of the base 100, there is a circuit board placement rack 200 for placing a circuit board. At the corresponding position at the bottom end of the outer wall of the base 100 and at the bottom end of the outer wall of the circuit board placement rack 200, there are fixed formed sliding seats 210. The provided circuit board placement rack 200 can slide on the top end of the outer wall of the travel guide rail 110 through the formed sliding seats 210, so as to be able to adjust the punctuation position of the circuit board. The formed sliding seats 210 are slidably connected to the outer wall of the travel guide rail 110. At the top end of the outer wall of the base 100 and on one side of the circuit board placement rack 200, there is a column 300. A fixed rack 310 is fixed on the outer wall of the column 300. The provided column 300 is used to fix the dotting component through the fixed rack 310. On the outer wall of the column 300 and on the side close to the circuit board placement rack 200, there is a dotting component for punctuating the circuit board. The dotting component includes a punctuation cylinder 330. At the upper end of the outer wall of the fixed rack 310 away from the column 300, there is an upper fixed plate 320. The bottom end of the punctuation cylinder 330 is fixed to the top end of the outer wall of the upper fixed plate 320. The provided upper fixed plate 320 is used to support the punctuation cylinder 330, and the provided punctuation cylinder 330 is used to drive the punctuation pen 351 to move up and down to perform dotting operations on the flexible circuit board;
[0022] A lower fixing plate 340 is fixed to the side wall of the fixing frame 310 and is located below the upper fixing plate 320. A moving frame 350 is arranged below the bottom end of the outer wall of the lower fixing plate 340. First through holes are formed at the centers of the upper and lower ends of the outer wall of the moving frame 350. A punctuation pen 351 for punctuating the circuit board is slidably arranged on the inner wall of the first through hole. A tightening bolt is threadedly connected to the front end of the outer wall of the moving frame 350 at a position corresponding to the punctuation pen 351. The inserted end of the tightening bolt abuts against the front end of the outer wall of the punctuation pen 351. When in use, the operator can insert the punctuation pen 351 into the first through hole, and then screw the tightening bolt to fix the punctuation pen 351 to the first through hole. An avoidance hole is formed at the position of the lower fixing plate 340 corresponding to the punctuation pen 351. Guide rods 352 are fixed at the four corners of the top end of the outer wall of the moving frame 350. The outer wall of the lower fixing plate 340 is slidably connected to the outer walls of the guide rods 352 through second through holes. The guide rods 352 are provided for guiding the movement of the moving frame 350 and can control the force through springs. Springs are respectively connected to the opposite outer walls of the moving frame 350 and the lower fixing plate 340 at the upper and lower ends. Springs are sleeved on the outer walls of the guide rods 352 and are located between the lower fixing plate 340 and the moving frame 350. A curved frame 353 is fixed to the right side of the top end of the outer wall of the moving frame 350. The upper end of the curved frame 353 is arranged above the top end of the outer wall of the lower fixing plate 340. The bottom output end of the punctuation cylinder 330 passes through the bottom end of the outer wall of the upper fixing plate 320 and is fixed to the top end of the outer wall of the curved frame 353. The curved frame 353 is provided to fixedly connect to the bottom output shaft of the punctuation cylinder 330 instead of the moving frame 350;
[0023] A cylinder piston 331 is arranged inside the punctuation cylinder 330. First sensors 332 and second sensors 333 are slidably arranged at both ends of the cylinder piston 331 on the outer wall of the punctuation cylinder 330. A group of magnetic rings can be arranged on the side wall of the cylinder piston 331. The first sensors 332 and the second sensors 333 are mostly magnetic sensors (Hall switches). That is, the Hall switches outside the punctuation cylinder 330 are fixed (but the positions of the Hall switches can be adjusted), and magnetic rings are installed on the cylinder piston 331 inside the cylinder (moving with the piston). When the magnetic rings on the piston move to the position of the Hall switch, the Hall switch outputs a signal to send an in-place signal. The signal sent will be transmitted to the driving main board of the device. The driving main board can control the time relay according to the signal fed back by the punctuation cylinder 330, and control the telescopic duration of the punctuation cylinder 330 through the time relay, so that the device can be reset in time after dotting to perform the next dotting.
[0024] The usage process of the present utility model is as follows: First, the personnel can install the device according to the above description. After the installation is completed, take out the flexible printed circuit board to be pressure-welded and place it on the circuit board placement rack 200. Subsequently, the personnel can perform pressure-welding processing on the flexible circuit board through the pressure welder placed on one side of the device. After the pressure welding is completed, the personnel can move the circuit board placement rack 200 to the lower part of the punctuation pen 351, and then control the punctuation cylinder 330 to extend through the driving main board, so that the guide rod 352 drives the moving frame 350 to move downward, and the punctuation pen 351 will contact the flexible circuit board to complete the punctuation operation. After the punctuation pen 351 completes the punctuation, the cylinder piston 331 in the punctuation cylinder 330 will be at the position of the first sensor 332, and the first sensor 332 will detect the magnetic ring on the cylinder piston 331 and send a in-place signal to the driving main board. The driving main board will time through the time relay. After reaching the input value, the driving main board will control the punctuation cylinder 330 to contract, so that the cylinder piston 331 is at the position of the second sensor 333, thereby enabling the personnel to complete the punctuation operation on the flexible circuit board. The personnel can also connect the device to the pressure welder through the IO interface, so that after the pressure welder completes the pressure-welding operation, the device can automatically start the marking component to perform the punctuation operation.
[0025] The above are only the preferred embodiments of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
